A) the additional contribution to this starlight by emission from hydrogen gas in the ISM. B) preferential scattering of blue starlight by fine dust grains. C) Zeeman shift of the light by the powerful magnetic fields existing within the ISM. D) scattering of this light from rapidly moving material, this light being Doppler-shifted toward the red end of the spectrum.
